He called that place Beer-sheba - באר שבע Beer-shaba, literally, the well of swearing or of the oath, because they both sware there - mutually confirmed the covenant.

Wherefore he called that place Beersheba,.... Either Abraham or Abimelech, or both, called it so; or it may be read impersonally, "therefore the place was called Beersheba" (t), for two reasons, one implied, the other expressed; one was, because of the seven lambs before mentioned; so the Targum of Jonathan,"and therefore he called the well the well of seven lambs;''"Beer" signifying a well, and "sheba" seven; the other, and which is more certain, being expressed, is as follows:

because there they sware both of them; by the living God, to keep the covenant inviolably they had made between them.

(t) "vocatus", V. L. Calvin, Piscator.

From this circumstance, the place where it occurred received the name שׁבע בּאר, i.e., seven-well, "because there they sware both of them." It does not follow from this note, that the writer interpreted the name "oath-well," and took שׁבע in the sense of שׁבעה. The idea is rather the following: the place received its name from the seven lambs, by which Abraham secured to himself possession of the well, because the treaty was sworn to on the basis of the agreement confirmed by the seven lambs. There is no mention of sacrifice, however, in connection with the treaty (see Genesis 26:33). נשׁבּע to swear, lit., to seven one's self, not because in the oath the divine number 3 is combined with the world-number 4, but because, from the sacredness of the number 7, the real origin and ground of which are to be sought in the number 7 of the work of creation, seven things were generally chosen to give validity to an oath, as was the case, according to Herodotus (3, 8), with the Arabians among others. Beersheba was in the Wady es-Seba, the broad channel of a winter-torrent, 12 hours' journey to the south of Hebron on the road to Egypt and the Dead Sea, where there are still stones to be found, the relics of an ancient town, and two deep wells with excellent water, called Bir es Seba, i.e., seven-well (not lion-well, as the Bedouins erroneously interpret it): cf. Robinson's Pal. i. pp. 300ff.

Wherefore he called that place Beersheba; because there they sware both of them.

21:31 Beer - sheba - That is, the well of the oath, in remembrance of the covenant that they sware to, that they might be ever mindful of it.

Beersheba: that is, The well of the oath

21:22-34 Abimelech felt sure that the promises of God would be fulfilled to Abraham. It is wise to connect ourselves with those who are blessed of God; and we ought to requite kindness to those who have been kind to us. Wells of water are scarce and valuable in eastern countries. Abraham took care to have his title to the well allowed, to prevent disputes in future. No more can be expected from an honest man than that he be ready to do right, as soon as he knows he has done wrong. Abraham, being now in a good neighbourhood, stayed a great while there. There he made, not only a constant practice, but an open profession of his religion. There he called on the name of the Lord, as the everlasting God; probably in the grove he planted, which was his place of prayer. Abraham kept up public worship, in which his neighbours might join. Good men should do all they can to make others so. Wherever we sojourn, we must neither neglect nor be ashamed of the worship of Jehovah.
